# List a tool's pin changes

GET

/v1/tools/{toolId}/pin-history

```sh
curl --request GET \
  --url 'https://example.com/v1/tools/example/pin-history?limit=25' \
  --header 'Authorization: Bearer <token>'
```

Every pin and unpin of the item, newest first: what each scope pinned before and after, who asked and why.

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.3.1/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**toolId**

required

string

ToolId — dotted namespace (`acme.lookup-order`).

### Query Parameters

**limit**

integer

default: 25 >= 1 <= 100

1..100. Default 25.

**cursor**

string

Where the previous page ended: its `nextCursor`, as it came. A runtime that seals cursors takes one only for the same list, filters and caller, within a day; otherwise `400 bad-input`, and the list starts again without it. Absent → first page.
